[latexrefman] Added fontenc

[Hefferon, Jim S.]

The alphabetically next entries in the .csv file are about encodings so I wanted to start with something about fontenc.  

Not sure where to put it; if there are a lot of commands then it may need to move but it is easy to move stuff once it is entered somewhere, so I put it in under output formats.  Alernate suggestions welcome.

Jim
